React Native:没有调试模式的时刻不适用于特定时间值 [英] React native : moment not working for specific time value without debug mode
问题描述
我在下面的代码中将时间值格式化为日期格式.
const 到达日期时间 = 时刻(`${todaysDate.format("YYYY-MM-DD")} ${arrivalTime}:00:00`,).迄今为止();
当调试模式关闭时,如果我从控件中选择 8 或 9 值,则无法格式化该值.
当我在调试模式下,选择 8 或 9 时,它能够将值格式化为:
2020 年 5 月 22 日星期五 09:00:00 GMT-0600(山区夏令时)
我已经看到许多讨论同一问题的线程,但其中提供的解决方案并没有帮助我正确地格式化它.
我正在尝试打印到达日期时间值,它在日志中显示如下;
日期 { NaN }
我正在尝试这个,但它不起作用,天 toDate 不是一个函数:
moment().format(`YYYY-MM-DD ${arrivalTime}:00:00`).toDate();
我花了一段时间,但我终于弄明白了.
这不起作用:
const 到达日期时间 = 时刻(`${todaysDate.format("YYYY-MM-DD")} ${arrivalTime}:00:00`,).迄今为止();
这有效:
const 到达日期时间 = 时刻(`${todaysDate.format('YYYY/MM/DD')} ${arrivalTime}:00`,).迄今为止();
//注意引擎似乎不喜欢用' - '解析.所以我把它改成'/'
仍然不确定背后的原因.
I have below code where I format the time value to be date format.
const arrivalDateTime = moment(
`${todaysDate.format("YYYY-MM-DD")} ${arrivalTime}:00:00`,
).toDate();
When debug mode is off, if I select 8 or 9 value from the control, its not able to format the value.
When I am in debug mode, and select 8 or 9, its able to format the value as:
Fri May 22 2020 09:00:00 GMT-0600 (Mountain Daylight Time)
I have seen many threads discussing the same issue but solution provided in them haven not helped me to format this correctly.
I am trying to print arrivalDateTime value, it shows like this in log ;
Date { NaN }
I am trying this but it does not work, it days toDate is not a function :
moment().format(`YYYY-MM-DD ${arrivalTime}:00:00`).toDate();
Took me a while but I finally figured it out.
This didn't work:
const arrivalDateTime = moment(
`${todaysDate.format("YYYY-MM-DD")} ${arrivalTime}:00:00`,
).toDate();
This worked:
const arrivalDateTime = moment(
`${todaysDate.format('YYYY/MM/DD')} ${arrivalTime}:00`,
).toDate();
// note that engine does not seem to like parsing with ' - '. so I changed it to ' / '
still not sure the reason behind it.
